Portable gaming laptop help

I have been searching for a gaming laptop for use as an addition to my desktop which is my main gaming device, but I cannot find a laptop which I want, it would be really helpful if some people gave some advice on this field
Specs:
Thin and portable

Decent sized screen (15" + but can be persuaded) with good resolution

Graphics which can run modern games like bf3 and run future games like gta5 and
crisis 3 On a level which isn't too painful and is where I can have fun on them

Budget under £1750 or about $2500 I think

Other specs:
Quite
Decent battery
Cool running temp
Looks good

I also don't need much storage as I will keep most files on my pc, so a decent SSd is a better option.

Thanks so much for taking the time to do this, it will really help and I'll buy a small game on steam for anyone who is really helpful and resolves my problem

Ps I am in the uk so razor blade and things can't deliver here before. Christmas
